After a few days I opened the project, I went back to work today, but when I opened the project I noticed that something was wrong because all the classes I open indicate an error by IDE , errors such as: / p>
can not solve symbol 'Activity', can not solve symbol 'Intent'
In other words, any import the IDE already shows error, I gave a clean in the project, it was no use. Has anyone had this?
I'm in the 1.5.1 version and the Java I have is the 7
D:\Program Files\Java\jdk1.7.0_79 .
The SDK of Android is all up to date.
